ABSTRACT:
Files are encrypted and stored on a WORM media device along with their encryption keys, the binary values of which are stored as a combination of written and unwritten sectors in a key storage portion of the media. To shred a file, the associated key is destroyed simply by writing into the unwritten sectors that are associated with the key.
